Question

1. choose three benefits of volcanoes.

wildlife benefit from the warmth of the lava.
peoples allergies improve when ash is in the air.
rocks shot out of the mountain can be used for building.
steam helps generate electricity.
ash creates rich, fertile land for growing crops.

Explanation:

1. Analyze each option:

• "Wildlife benefit from the warmth of the lava": Some wildlife can adapt to volcanic areas and use the warmth, though it's not a primary major benefit compared to others, but still a benefit.
• "People's allergies improve when ash is in the air": Volcanic ash in the air usually worsens allergies, so this is incorrect.
• "Rocks shot out of the mountain can be used for building": Volcanic rocks (like basalt) are useful construction materials.
• "Steam helps generate electricity": Geothermal energy from volcanic steam is used to generate electricity.
• "Ash creates rich, fertile land for growing crops": Volcanic ash is rich in minerals, making soil fertile.

1. Select three valid benefits: From the above analysis, "Rocks shot out of the mountain can be used for building", "Steam helps generate electricity", and "Ash creates rich, fertile land for growing crops" are valid. Also, "Wildlife benefit from the warmth of the lava" can be considered, but the three more significant and commonly recognized benefits are the latter three or including the wildlife one. But based on typical volcanic benefits, the three main ones are the use of rocks for building, geothermal steam for electricity, and ash for fertile soil.

Answer:

• Rocks shot out of the mountain can be used for building.
• Steam helps generate electricity.
• Ash creates rich, fertile land for growing crops.
